SGA-3563Z

The SGA-3563Z is a high-performance Silicon Germanium Heterojunction Bipolar Transistor (SiGe HBT) Monolithic Microwave Integrated Circuit (MMIC) Amplifier from SIRENZA. It features a Darlington configuration with 1-micron emitters, providing high transition frequency (FT) and excellent thermal performance. The heterojunction design enhances breakdown voltage and minimizes leakage current.

Key electrical specifications include a typical gain of 25.5 dB at 850 MHz, a high output IP3 of 24.5 dBm at 1950 MHz, and a low noise figure of 2.7 dB at 1950 MHz. The device operates with a low typical current draw of 35 mA from a single positive voltage supply. It requires only a single positive voltage supply, two DC-blocking capacitors, a bias resistor, and an RF choke for operation.

The SGA-3563Z is available in a lead-free, RoHS compliant green package (Z suffix) with a matte tin finish applied using a post-annealing process to mitigate tin whisker formation. The package body is manufactured with green molding compounds that contain no antimony trioxide or halogenated fire retardants. This amplifier is suitable for applications such as PA driver amplifiers, cellular, PCS, GSM, UMTS, IF amplifiers, and wireless data systems.
